To all whom it may cone m l Be it known that I, HENRY ADAMS, a citizenof the United States, residing at Stam- 'ford,"in the county ofFairfieldi'and State below the ,point where the material will 1 ofConnecticut, have inventedfcertain new and useful Improvements inCentrifugal Crushers and Separators; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to\ improvements in centrifugal crushers andseparators and more especially for crushers of fi-iableminerals andores, particularly for anthracite coal where the least amount of finesor pul-- verized' product is desired as the ,result of a s' gleoperation.

he primary objectoftheiinvention is to provide an apparatus of. thischaracter which may be simply and inexpensively constructed and whichwill efl'ectively,per-

form the functions for which it is designed;

Another object of the invention is to pro-. vide an apparatus which willnot only break and crush the material treated but will automaticallyclassify it after it is broken.

Another object is to provide an apparatust in which one blow only isstruck .on one side of thezmaterial at one time and which never subjectsanyone piece of material at the same'time toia crushing force on oppo- Asite sides thereof; nor permits-two pieces adjustably mounted angleplate which is,

placed around the face of the anvil. just strike the anvil, afterit'leaves the revolving table and is thereby directed into suitableplaces of deposit.-

With these and other ob ects in view, the invention consists of'certainnoyel features of construction, and the combination and. arrangement ofparts as will be more fully described and claimed.

In the accompanying drawing is shown a vertical central section of theapparatus.

machines used in the last instance} This apparatus comprises a revolubleI to omit these corrugations, and provide a plane surface for the table.An anvil 7 surrounds this table 1 and is here shown annular with the;striking face 8 thereof, which is arranged opposite the periphery of thetable 1, being shown perpendicular and in a plane at right angles tosaid table.

The distance this striking face 8 is disposed from the periphery of thetable may be varied, depending on, the material to be treated. As shown,this annular anvil 7 is mounted on wheels 9 which travel on a circulartrack 10 and said anvil may be revolved by any suitable means (notshown) either in tKesa'me direction or in-an oppo- I site direction tothe line of travel of the revolving table 1. The striking face 8 of thisanvil maybe plane corrugated or toothed as desired, depending on thematerial'to be treated.

Disposed around the inner face of the anvil with its top positioned justbelow its striking face 8, is ;a circular adjustably mounted guide plate11 which may be supported in any suitable or desired manner g and whichinclines downwardly and out wjardly from its upper toward its inner edgeto receive and direct "the material after it strikes the face 8 of theanvil, so that it will be guided into suitable bins below as will behereinafter described,

The coal, coal and bone mixed, slate and rock, are all of difierentweights and hence, they will slide downthe guide plate 11 withresistance and the hoppers that. are placed lot a velocity proportionatp0 their frictional below the guide plate are positioned so that eachpiece of material will fall into its proper hopper, This guide plate 11may be" adjusted up and down on the arivil 7 by any first piece struck,strikes the anvil laterthan shown provided for this purpose but anyother means may be employed which will 9 operate to vary the verticalposition relative to the anvil to position it at the desired pointthereon relative to the striking face thereof. b 1 1 v lheturn buc es 12connect the two 'rod sections 12: an 12" .and are designed to vary thelength of the connecting rod 12*, of which they form' a part. One end ofeach rod 12 is connected with the plate 11- and the other end with oneof a gertically dis- 5 posed series of spaced apertures 8' formed inthe'face 8 of the anvil 6 provided for the vertical adjustment of saidplate 11.

Disposed around, and inside of the anvil .7 at po' ts spaced therefrom,are a plurality go of spa ed circular hopper-like members 13,

14, 15 and 16 which are placed in suitable pos'tion to receive thebroken material when it allsfrom'the'guide plate l1 and which; operateto direct the material'into' suitable receivin bins 17 arranged belowsaid hop- V pers, w ereby the material is automatically classified,proportionately toits frictional resistance, the lighter going fartherthan the heavier. -The heavier particles meet-with '30 greaterresistance and hence move ata slo'wer speed and consequently fall intothe hopper 16 which is disposed directly below the edge of-the'plate 11and which passes it on into the bin below it and the smaller piecesaccording ,to their size and weight will be directed into the otherhoppers, the heavier pieces traveling less distance than the lighter. pv The heavier impurities, such as slate, bone 40" and rock and otherforeign matter which will not break on striking the anvil 01:, if

broken, will be in large pieces, will have a greater angle of reboundthan the material crushed and will 'consequently fall farther 46 downand be directed into abin f 18 'positioned to receive such waste andthus tautomatically separate it from the coal 9r other material beingtreated, leavin the latter a pure unadulterated-state." the appara- 'tusshown,'four-receiving bins anddirecting hoppers therefor ,are employedbut it isob- 'vi'ous that any desired number may be used. v The guideplate 11 is designed to prevent 1 the coal or other material afterit-has been 56 broken by thetnvil -7,' from contacting with each otherand from receiving av crus g low from any other means and direct it. 4into the hoppers with the least possible breaking force .to eliminate-asfar as possible, the production of fines and pulverized suitable means,turn buckles 12 being here the first piece and as these pieces fall onthe edge of the table I and the anvil, 7, in order that each pieceofmaterial after it strikes the anvil absolutely leaves the machinewithout beingsubjected in any way to any further crushing force, such aswould occur if this continuous outlet were not provided and hence, theinainobject of the apparatus will beiaccomplished, which is to preventthe material from receiving more than one blow on one\side thereof andto prevent two or more pieces from striking against each other.

In the operationof this apparatus, coal 90. or other material to betreated is fedto the upper facepf the table 1 near the center thereof byany suitable feeding means not shown) and said coal is carried outwar othe periphery of the table by centrifugal action andis thrown if thetable a radial direction, he face 8 of he anvil just above theguideplate. 11 and onto which the broken pieces fall and are directed intothe. respective'hoppers and conveyed thereby" into the classifying binsarranged below them. a

As the material is fed on the revolving table, the centrifugal actioncarries it tothe' periphery and the material being fed onto said tablewith a regular feed, only one piece 'will leavefthe periphery at onepoint and this piece strikes the anvil nearly opposite the place whereit'leavesjtheperiphery of the table'. The next piece 'stnking'the anvilat that point will strike it later than the first piece mentioned and soon. As the material vbreaks on theanvil it falls onto v the guide plate11 by which it is immediately conveyed to the bin designed to receiveit. As this guide plate 11 is disposed at anangle sloping downward, thematerialis classified on this plate according to the frictionalresistance afforded by the plate. It is obviousmaterial. The moinentthe-icoal' is broken' hammer heads and the like, which do not on theanvil '8, it falls onto the guide plate 11 and the pieces are,immediately carried away. The next piece of coal that is broken on theanvil at-the' same place where the break on comin in contact with theanvil face8 'or break only in large pieces, will thus be eaused tofollow a line of travel'which is farther down and outward than any of'the hoppers and consequently, will be directed into the bin 18 arrangedto receive it. .The hopper-like members 13, 14, 15 and 16 are .hereshown of difierent heights, the innermost member being lower than theothers. and the others gradually increasing in height toward theoutermost member 16 to readil receive the different sized pieces ofmaterial discharged from the guide plate.

I claim In a centrifugal crusher the combination of a revoluble memberfor receiving the ma terial to be treated, an anvil disposed oppo:

sitesaid member and spaced therefrom, an

angularly disposed guide arranged adjacent 15 In testimony whereof Ihave hereunto set 20 my hand in presence of two subscribing witmesses.-
